A system of low-orbiting communication satellites that can share radio spectrum with geostationary satellites and methods mitigating interference to enable sharing are disclosed. In some embodiments, the satellite progressively tilts as it travels along its orbit, or its transmission beams are mechanically or electronically tilted. As a consequence of the tilting, as a satellite approaches the equatorial plane, its transmission beams are aimed more and more toward the equatorial plane, compared to when the satellite is far from the equatorial plane. Using this technique, an angular separation sufficient to prevent interference between the satellite's radio signals and GEO radio signals at all satellite positions is maintained, and, as a result good coverage is provided to all ground locations. |
